A data analyst needs to generate all possible combinations of product sizes and colors for a new catalog. The `sizes` table has 5 rows, and the `colors` table has 8 rows. The analyst wants a result with 40 rows, each representing a unique size-color pair. Which query should the analyst use?

SELECT * FROM sizes LEFT JOIN colors ON sizes.size_id = colors.color_id

SELECT * FROM sizes CROSS JOIN colors

SELECT * FROM sizes FULL OUTER JOIN colors ON sizes.size_id = colors.color_id

SELECT * FROM sizes INNER JOIN colors ON sizes.size_id = colors.color_id

Which of the following is an example of ANSI JOIN syntax?

SELECT * FROM a, b WHERE a.id = b.id

SELECT * FROM a WHERE a.id IN (SELECT id FROM b)

SELECT * FROM a INNER JOIN b ON a.id = b.id

SELECT * FROM a UNION SELECT * FROM b
